초록
들깻잎의 메탄올 추출물은 Salmonella typhimurium TA98과 TA100균주에서 AFB$_1$, Trp-P-2 및 B(a)P의 돌연변이유발을 억제시키는 효과가 있었으며 이들을 용매로 더 분획 했을 때 수층에서는 효과가 없었지만 헥산획분과 부탄올 획분에서 항돌연변이 효과가 있었다. Lipid peroxidation은 들깻잎의 메탄올 추출물을 첨가하였을 때 억제되었으며 특히 부탄올 획분 첨가시 크게 억제됨을 관찰할 수 있었다. 돌연변이 유발억제 및 항산화 효과가 관찰된 부탄올 획분에서 2-propyl furan, ethanodioate, dibutyl ester, benzaldehyde, 2-methyl-2-ethyl-3-hydroxy-propanoic acid, octahydro-3a-methyl-2H-inden-2-one등이 잠정적으로 동정되었다.
The methanol extracts of perilla leaves reduced the mutagenicities mediated by of aflatoxin B$_1$(AFB$_1$), 3-amino-l-methyl-5H-pyrido (4,3-b) indole (Trp-P-2) and Benzo(a)pyrene (B(a)p) in Salmonella typhimurium TA98 and TA100. The methanol extracts were more fractionated, and the fractions of hexane and butanol revealed the antimutagenic activities against AFB$_1$ and B(a)p. The production of malondialdehyde (MDA) was decreased when the methanol extracts of perilla leaves were added to the system. The significantly higher antioxidative activity was observed in the butanol fraction. 2-Propyl furan, ethanedioic acid, dibutyl ester, benzaldehyde, 2-methyl-2-ethyl-3-hydroxy-propanoic acid and octahydro-3a-methyl-2H-inden-2-one were identified tentatively as major compounds from the butanol fraction.
